GAS-BURNER.

SPECIFICATION forming part of Letters Patent No. 638,044, dated November 28, 1899.

Application filed September 7, 1898. Serial No. 690,402. (No model.)

Be it known that I, PHILIPB. CURRAN, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Gas-Burners, which improvement is fully set forth in the following specification and accompanying drawings.

My invention relates to an improvementin a gas-burner which is provided with a mantle; and it consists in so constructing the support of said mantle that shocks to the latter will be prevented from fracturing or breaking the same.

Figure l represents a side elevation of a gas-burner embodying my invention. Fig. 2 represents a central vertical section thereof.

Similar letters of reference indicate correspending parts in the drawings.

Referring to the drawings, A designates a sleeve within which is the perforated plug B, which is surmounte'd by the perforated cap C, at which latter the gas is burned, the upper portion of said plug being formed of the tube D, which is of reduced diameter and has the gas-chamber E around the same, said tube having ports F therein, whereby gas entering the plug B may be directed to the cap both through the tube D and the chamber E.

Below the sleeve A is the sleeve or chamber F', which supports said sleeve A and is supported on the vertically-arranged flue G, whose lower end has secured to it the hollow foot H, which is freely fitted in the collar J, so as to be permitted to rise and lower therein,

said foot resting on the coiled spring K, which' is sustained on the base-plug L, in which is the gas-inlet port M, which, as will beseen, is below the foot H, said plug L being adapted to be secured to a suitable fixture.

The collar J is screwed or otherwise secured to the plug L and is surrounded by the rotatable sleeve N, which is freely supported on the shoulder P on the periphery of the plug L.

In the collar J are ports Q for the admission of air into said collar, the latter constituting the gas and air mixing chamber of the burner.

' In the sleeve N are ports R, which are adapted to be placed partly or entirely in register with the ports Q of the collar J in order to regulate the proper amount of air to be supplied to said sleeve.

Secured to the upper end ofthe collar .I above the foot- H is the coiled spring S, which supports the ring T, the latter' freely encircling the flue G. The said ring T encircles the iiue G about midway between its ends and furnishes a guide 'or support therefor-that is to say, the ring, under the influence of spring S resists the tendency to lateral vibration and serves as a guide through which said flue can move longitudinally when it vibrates vertically upon the resilient cushion K.

The hollow foot H is provided with a laterally-projecting flange which freely contacts with the interior of the collar J and guides the fine G in its vertical motions while being supported on the spring K as a cushion, but said iiange presents a short surface, permitting the iiue G to roll on said surface without strain, gently resisted by the encircling ring T, which has the resilient support S.

It will be seen that the combined gas and air in the chamber formed by the collarJenters the foot H, the flue G, the chamber F', and the plug B, yand so reaches the cap C, where it may be consumed.

Should there be any vertical shocks imparted to thefburneig-the parte above the spring K may yield and vibrate with the latter in Vertical direction. Should there be any lateral shocks imparted to the burner, said parts will yield in that direction, limited by the side pressure thereon of the spring S. In either case the shocks are prevented from being injuriously communicated to the mantle supported on the burner. In the absence of shocks the springs K and S retain the aforesaid parts of the burner in upright and properly-elevated position without affecting the operation of the burner.

On the stationary base or base-plug L is supported the annulus U, which enters the lower-portion of the spring K and serves to steady the same, while, however, not interfering with the free passage of gas and air therethrough. Said annulus is supported ou legs V, which are separated and secured to a base L, the spaces between said legs being in communication with the mixing-chamber, so that should the convolutions of the spring K IOO : Gasp-14'.

close above said annulus, due to severe downward pressure thereon, gas and air will be permitted to enter said annulus from below and so pass through the spring to the flue G, it being noticed that the lower convolution is rigidly connected with said annulus, and thus the spaces, as aforesaid, remain uncovered at all times.

The cap C is separated from the sleeve A by the space W, forming a passage for gas from said sleeve, so as to increase the supply of gas at the place of combustion, as the perforations of the cap are not sufcient for such supply. It is evident that the gas issues through the perforation@ in the cap both on the inside and outside of the tube D and also through the space or annular slot W, thereby affording an ample supply of gas to furnish a large flame, while the space or annular slot W serves to direct the outside of said iiame against the sides of the mantle.

Owing to the construction of the plug B and adjacent portions, while the proper supply of gas is maintained at the cap C gas is prevented from returning ignited to the inlet-port M.

The spring S is preferably conical, so as to produce the effects in causing the flue and connected parts to resume and retain their normal positions.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a gas-burner, the combination with a stationary part provided with a chamber at its upper end, of a mantle-support having its lower end iitting freely within said chamber with its edges forming a joint with the walls thereof, whereby said mantle-support can move longitudinally and roll laterally upon said joint, a resilient cushion upon which the mantle-support is mounted, and a guide sustained above said stationary part by a laterally-resilient cushion and throughwhich said mantle-support freely passes.

2. In a gas-burner, the combination with a stationary part having a chamber at the upper end thereof, said chamber being open at its upper end, and a guide situated above the same and sustained by a laterally-resilient cushion fastened to said stationary part, of a mantle-support passing through said guide and provided at its lower end with a foot or enlarged portion fitting loosely within and against the sides of the chamber of the stationary part and sustained longitudinally by a resilient cushion. 3. In a gas-burner, the combination with a stationary part having a chamber at the upper end thereof, said chamber being open at its upper end, and a guide sustained above the end of the same by a spring, the lower end of said spring being secured to the upper end of said stationary part, of a mantle-support passing through said guide and having its lower end fitting loosely within and against the sides of said chambered upper end of the stationary part, and a spring situated within said chamber and upon which the lower end of said mantle-support is mounted.

4. In a gas-burner, the combination witha stationary part, a spring secured to the upper end thereof, and a guide-ring carried by the upper end of said spring, of a longitudinally and laterally movable mantle-support passing freely through said guide-ring.

5. In a gas-burner, a sleeve, a perforated plug situated therein, said plug being smaller than the sleeve to provide an annular chamber, and a cap upon the upper end of said plug, said cap being smaller than said sleeve to provide a space or annular slot, and said cap being provided with perforations above said tube and the annular surrounding chamber.

6. In a gas-burner, a base provided with a gas-inlet port and having a chamber receiving the lower end of a longitudinally-movable flue leading to the burner, and a spring having its lower end supported a little distance above the gas-inlet support of said base, the upper end of said spring sustaining said flue.

7. In a gas-burner, a base provided with a gas-inlet port and having a chamber receiving the lower end of a longitudinally-movable flue leading to the burner, an annulus supported above the upper end of said base, and a spring having its lower end secured to said annulus, the lower end of said burner-flue being mounted upon the upper end of said spring.

8. In a burner, a collar, a perforated base therefor, a cushion supported on said base, and agas-flue resting on said cushion, in cornbination With a cushion supported on said collar, and a ring freely around said flue resting on the latter-named cushion, said flue having on its foot a laterally-projecting liange which freely engages with said collar and permits the flue to roll on thelatter.

9. In a burner, a Iiue, a collar in which the same is permitted to fall and rise, a perforated base for said'collar, and a cushion supported on said base, in combination with an annulus within said collar at the bottom of said cushion, the same being supported above said base with an intervening space between said annulus and base.
